The Four Corners series is perfectly suited to today’s commute and tomorrow’s touring adventures. The butted 4130 CrMo steel frame and fork are designed to handle fully loaded touring, with up to six bottle mounts, rack and fender eyelets, lowrider fork mounts, generous tire clearance and disc brakes to bring it all to a stop. Marin updated the geometry based on biometric fit data, and for 2019 offers five different frame sizes with size proportionate 650B or 700C wheels to properly fit riders between 4’11” – 6’4”. The bars are set high for all-day comfort and heads-up visibility in traffic, with mountain steering geometry capable of taking you down whatever path your destination requires. Carry a laptop and change of clothes during the week, a tent and camp stove come Saturday morning. Get to work, and get out of town.

The Four Corners is available in five frame sizes to fit riders 4’11 to 6’4” without compromise. For proper fit and bike handling sizes XS and S use 650B wheels, sizes M, L, and XL use 700C.
New for 2019 are fork leg bottle or accessory cage mounts, along with traditional front triangle bottle mounts (three on sizes M-XL, two on XS-S) for up to six bottle cage mounts total.
The Four Corners has separate fender and rack mounts on both the frame and fork to fit a variety of aftermarket accessories securely and without interference with one another.
The Four Corners uses a double butted and formed 4130 CrMo frame specially tuned for loaded touring with upright geometry for comfortable and efficient all-day rides.
Disc brakes provide smooth, controlled stopping in all conditions with minimal maintenance.

"If you’re a commuter or utility rider who wants to do some touring on the weekends, the Four Corners is solid candidate. With a change of tires it’s also a capable dirt-road explorer. A few short years ago a bike of this caliber this would have sold for much more. But despite its base-level designation, the Four Corners performs well above its price point. It’s so capable, in fact, that I often found myself inadvertently comparing it to bikes retailing for $500-$1000 more. Sure, those more expensive bikes might be a little lighter, and come spec’d with fancier components, but the Four Corners gives up nothing when it comes to function and versatility."

"The mark of a good adventure bike is how easily it can go from dirt roads and gravel paths to the city streets of a daily commute. Marin's Four Corners bike is optimized for comfortable multi-terrain touring, with a long, tall frame that steers slowly and has extra braze-ons for storing cargo without sacrificing balance and speed."
